Our project is to conduct a semi-structured interview and find out what matters to the users when using online foreign exchange system, so that we can redesign the system of Megabank. First, we found several people who ever used online foreign exchange system and interviewed them about how many bank accounts they have and how they use each bank account. All interviewees have at least three accounts and use the accounts for time deposits, investment or buying foreign currencies.​
          Later, I discovered that the user1 only uses online foreign exchange system when she is going to travel abroad. She is very familiar with overall process and feels quite satisfied with the application. It’s worth mentioning that the user1 spent relatively more time on checking and comparing the exchange rate.
          When user2 used the online system, it was very important that the system was easy and hassle-free to operate. Then, I asked her to perform some tasks to observe the actual usage. I found that when calculating, even though the webpage provided a calculator, she still preferred to do the calculations mentally or using a physical calculator, partly because of the user2's long-standing habit, and partly because when using the webpage calculator, she could not refer to the exchange rates of other currencies at the same time, or could only calculate one currency at a time, making it more difficult to make comparisons.
          Moreover, I observed that user3 is good at using this system, but she was sometimes confused by the proper nouns, and then slow down her action to think. I further found that she ignored some function and button that showed on the page.
          The insights we found is that three users are all know the steps while exchange currency with those system, and they usually think about what they want to do before using those systems. We further found that they would rather follow their usage habits than try other functions that showed on the page.
